Gaining weight from sleeping in the cold?

I looked it up in a medical guide. Appears you are going through menopause. Heat flashes are next.

Good, that should decrease my pack weight when I drop a fleece from my kit.

Have you been drinking beer? That will add weight too.

No more than usual. Once a week I'll have 3-5 beers with friends at the bar. All fall and spring of 2012, I drank maybe 10-15 per week because that was my "be a college student" year. I gained nothing. I ate pretty unhealthily.

This summer I went vegetarian and went from 165 to 158, then ate more cheese and bread and went back to 165 by… I think October. So I guess I've put on 4lbs but what I'm really wondering is if there's a fat layer storing because of the cold.

The likely answer is "You set a record for Mashed Potatoes Consumed on Thanksgiving, big boy."

But I would be much more delighted if it turned out to be a physiological response for survival.

Either way, I'm sure it'll fall off.

Face it Max, you're getting older. It's the beer.

Yeah, I can't find anything online other than a scientific study that showed humans in colder climates adapted to be rounder because it decreased their surface area for better heat retention. Since i'm not inuit, I'm just older.

Whatever! An extra 5lbs to train muscles on, and polar bear fat for winter!

Papa don't preach; I'm keepin' my baby until Spring.

Make sure you weight yourself at the same time, with the same clothes and "conditions". Most people are the lightest in the morning after their first "bathroom break" and before eating or drinking anything. You can easily vary as much as 4 (or more) pounds during a single day.
